Detailed Description

template<class StoredType>
class misc::xalloc< StoredType >

Allocate slots in std::ostreams.

Used to store flags in streams so that calling print with additional parameters is no longer required (for example in ast/libast.hh).

Set, get or swap data. The idea is to build the right inner class with set, get or swap methods, then use this class as a parameter of operator<<.
